Description

（１）本発明の一形態は、燃料電池スタックである。この燃料電池スタックは、燃料電池セル積層体と、前記燃料電池セル積層体の端部に配置されたエンドプレートと、を備える。前記エンドプレートは、金属製の板状本体と、前記板状本体の面に形成された樹脂層と、を有する。前記板状本体は、反応ガスおよび冷却媒体用の流路孔と、前記板状本体の前記面から隆起する筋形状の凸部であって、前記流路孔を含む内側領域と、前記内側領域の外側の外側領域と、に区画する凸部と、を有する。前記凸部は、前記板状本体の前記面から隆起した垂直部と、前記垂直部の先端から前記内側領域側に張り出した出っ張り部と、を有する。前記樹脂層は、前記内側領域に形成され、前記垂直部における前記内側領域側の面と、前記出っ張り部の少なくとも一部と、を覆う。 (1) One aspect of the present invention is a fuel cell stack. The fuel cell stack includes a fuel cell stack and an end plate disposed at an end of the fuel cell stack. The end plate has a metal plate-like main body and a resin layer formed on the surface of the plate-like main body. The plate-shaped main body is a flow path hole for a reaction gas and a cooling medium, a streaky convex portion protruding from the surface of the plate-shaped main body, and includes an inner area including the flow path hole and the inner area. with the outer of the outer region, and a convex portion that partitions a. The convex portion includes a vertical portion that protrudes from the surface of the plate-like main body, and a protruding portion that protrudes from the tip of the vertical portion toward the inner region. The resin layer is formed in the inner region and covers a surface of the vertical portion on the inner region side and at least a part of the protruding portion.
